Research on matter with brilliant light sources
BESSY II produces brilliant synchrotron light and is optimized for spectral ranges vacuum UV to soft X-rays. Its instruments permit experiments at high-resolutions: spatially to 10 nanometers, temporally to 100 femtoseconds, and in the spectral range down to milli electron volts. All instruments and the accelerator systems are continually upgraded. Energy research has become an important focus.
Currently are 39 instruments in operation, including FEMTOSPEX, 1²/1³ ARPES, X-ray microscopy, RICXS, MX and EDDI beamline, S-PEEM, ARTOF in pseudo single bunch, THz-EPR.
The newly build Energy Materials In-situ Laboratory (EMIL) is directly connected to two dedicated beamlines at BESSY II.
Each year, approx. 5,200 hours of user operations, 2,500 measuring guests, and 400 publications. Helmholtz programmes using BESSY II: MML, EMR, FIT, and various cross-programme activities.
With BESSY-VSR, the concept for a variable pulse length storage ring (planned start of operation 2020) is being developed. bERLinPro provides a feasibility study for a "Energy Recovery Linac" with a view to a successor light source BESSY III (2028+).
